MACHINE FOR WELL-BORING AND DRILLING.

SPECIFICATION forming part of Letters Patent No. 403,097, dated May 14, 1889.

Application filed April 12, 1888- Serial No. 270,477. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES S. GARDINER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machinery for Well-Boring and Rock-Drilling, of which the following is a specification.

My invention relates to machinery designed to operate a rock-drill, or an auger used for well-boring. Such machinery is so constructed that the drilling is effected by a lifting and automatically-tripping device, and the boring by simply disengaging such device from the rest of the machinery and then operating the machinery as before.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the rockdrilling and well-boring machinery which constitutes my invention. Fig. 2 is a vertical longitudinal section of the same, taken on the line 1 1 in Fig. 1. Fig. 3 is adetail elevation of the eccentric and eccentric-wheel which operate the drill. Fig. 4 is a detail elevation of the eccentric and eccentric-wheel and the inner end of the Windlass with the operatingfingers. Fig. 5 is a vertical section of the upper end of the drill-shaft with the loosening device; and Fig. 6 is a plan section of the machine, taken on the line 2 2 in Fig. 2.

The same letters refer to similar parts throughout the several views.

Referring to the drawings, A is the framework which supports the operative machinery. This is designed to be mounted and secured upon cross-timbers on the trucks of a wagon, so that the machine may be operated on such wagon and may be easily transported from place to place.

A is a circular trackway, rabbeted on its inner side and furnished with cogs beveled toward their outer ends, whereon the operative machinery revolves when in use.

B B are beams, designed to support the pulley C, by the revolution of which the drillshaft is lifted. These beams stand on the casting A being secured to it by the hinges a. At their tops the beams are fastened together by any suitable means, and secured in position by the guys a, which guys may be fastened at their lower ends to stakes driven in the ground.

At the center of the trackway A is the circular casting A having a vertical opening through it to allow the passage of the drillshaft D, and having two spokes. .The casting A has at its center'a hub which encircles the central part of the casting A when in position ready for work. This hub restson the anti-friction rollers" a journaled on set-screws extending into the ring A encircling the cast ing A'.

The arms of the casting A are secured at their outer ends to the frame A Levers for the application of power are secured to the frame A at the points where the arms of the casting A meet said frame. Said levers are preferably of wood. They extend horizontally outward from the frame and are fitted with suitable attachments at their outer ends to hitch horses or other draft-animals to for the purpose of operating the machinery. The

' guys P, extending from the upper ends of the beams B, support the outer ends of the levers. E is a shaft journaled at its outer end in journal-boxes in the frame A and at its inner end in a socket-bearing in the casting A E is a Windlass revolving on the shaft E. It has on its outer end a collar to fit in the rabbet of the trackway.

E is a pinion on the outer end of the windlass, beveled toward its inner side. Thus by the action of this bevel and the collar above mentioned the Windlass is held securely in its destined course.

On the periphery of the inner end of the Windlass are the dovetailed lugs c. On these lugs are secured the dovetailed finger-pieces e.

F is an eccentric-wheel keyed on the inner end of the shaft E.

F is an eccentric within which the eccentrio-wheel F turns, the eccentric-wheel F being all the time in contact with the eccentric F.

G and G are respectively a Worm and a worm-wheel, the former gearing into the cogs 1c:

of the latter. The wheel is keyed on the shaft E and is designed to operate the eccentricwheel F.

It is obvious that by operating the worm G the eccentric-wheel F will be revolved and the eccentric F raised or lowered. Thus the time that the lug f will be in contact with a finger, 6', will be increased or diminished. By the same means the former maybe thrown completely beyond the reach of the latter, which is done when the machine is used for boring instead of drilling.

II is a shaft resting in journal-bearings corresponding to those designed for the shaft E.

II is a beveled pinion similar to the pinion E rigidly secured upon the shaft H.

H is a gear-wheel rigidly secured to the pinion H and provided with a collar designed to revolve in the rabbet of the traclnvay.

h is a gear-wheel of half the diameter of the wheel H engaging with said wheel and keyed on the short shaft h, which revolves in a suitable journal-box mounted 011 the casting A H is a gear-wheel equal in diameter to the wheel H and keyed on the shaft h.

72 is a gear-wheel equal in diameter to the wheel 72., engaging with the wheel II, rigidly secured to the wheel H and revolving with it on the shaft H.

II is a balance-wheel loosely mounted on the shaft II, and a set-screw passes through its hub, by tightening which it will be made to revolve when the shaft I-I revolves. The design of this wheel is to secure steadiness in the action of the machinery. It is obvious that its velocity will be quadrupled by loosening its set-screw and connecting it with the wheel 7L \Vhen only the velocity of the shaft h is desired, the set-screw is tightened, and the wheels H and 71 are detached from the machinery.

I is a weight having an aperture large enough to allow the drill-shaft to pass up and down through it, and having flanges on opposite sides to travel in the guides I on the inner sides of the beams B. This weight is designed by its striking force to aid the pulleyO in loosening the drill after it has struck a blow. To this end it has the lifting-rods 2', which pass up through the cross-head J, to which is secured the cord K, which passes over the pulley C. To regulate the length of the upward stroke of the weight I, the rodsz' being rigidly secured in the weight are screwthreaded a sufficient length at their upper ends and pass through nuts on either side of the cross-head.

K is a cord secured to the cross-head J, passed up over the pulley C and down and around the hook L, so as to be secured to it. This cord is suificiently long to extend down to the windlass E, so as to be secured to it in any suitable manner. lVhen not in such use, its surplusage can be wound around a pin secured in the frame-work at any suitable point, as at a: in Fig. l. The cord K secured to the hook. L, passed down around the pulley M, pivoted on a shaft secured in the adjacent beam B, and then to the upper angle of the eccentric F, where it is securely fastened. The hooks L and L are secured to a bar, N, which passes up and down in the guides N, secured to the adjacent beam 13. 7c is a cord secured to thelower angle of the eccentric F, passing around in the groove in this eccentric, up under the pulley M to the spring 0, to which it is fastened. To the upper end of'this spring the cord k is fastened, and then passes over the pulley M secured to the said beam B, and down to the hook L, to which it is fastened.

The operation of the above-described machinery is as follows: If the work to be done is drilling, before starting the machinery the shaft E is turned by actuating the wormwheel G, so that the eccentric-wheel F will lower the eccentric F till the lug f on the eccentric will engage with the fingers c. As the revolution of the machineryproceeds, the pinion E and the windlass E will revolve about the shaft E. Thus the lugs e, and with them the fingers 6, will be carried around, the latter will engage with the lug f on the eccentric F, and this lug will be carried downward, and along with it the cord K, the hook L, the bar N, the hook L, and the outside part of the cord K. Thus the pulley G. will be turned, and the cross-head J, weight I, and drill-shaft D will be lifted. It is obvious that as the weight I, rising, reaches the under part of the head of the drill-shaft, it will, by virtue of its momentum, exert a striking force upward, and will thus aid in loosening the drill. As the finger e descends, it will pass below the lug j, and thus all the above-described lifting elements will be released, the drill-shaft willdrop, and the drill will do its work. When the above release is eifected, the spring 0 will prevent too sudden reaction of the lifting elements. The cord and its continuation in the spring 0, and the cord 7t, prevent the eccentric F from reacting too far, holding it so that the lug f will remain at the left (as viewed in Fig. 1) of the longitudinal axis of the beam B. The frequency of the stroke of the drill will be determined by the number of the lugs c that are fitted With the fingers c. Ky elevating the eccentric F so that its lug f will not engage with the fingers e, the machinery can be revolved without actuating the drill. Then the cord 7.: can be detached from the hook L and the part that was coiled around the pin a; may be taken down and its end secured to the windlass E, which, as it revolves, will wind the cord around it, and thus lift the drill continuously. This will be found convenient, especially when boring deep wells.

It is obvious that when the above adj ustment of the eccentric F has been made the machinery will be ready for boring when an anger has been substituted for the drill.
